Abstract
•Polyzwitterion with a sticky catechol chain end is successfully synthesized.•The polyzwitterion adheres to various substrates to form thin hydrophilic coatings.•Coated mesh/membrane is efficient in separating oil/water mixtures/emulsions.•Coating is fouling-resistant and stable under harsh environments.
